  Ray,

Likr all IP addresses, there are 4 bytes.  all AMPR.ORG addresses are in net
44.0.0.0.   Therefore, his address _could_ be 44.66.??? ie..anything!!  In a
previous posting, the address coordinator for 44.066 was John DeGood NU3E
in Delaware.   You can contact him.  Maybe finger [e-mail] will return
something usefull.

Just a starting point, cause you dont have enough info to address a mail message!

Additionally, the ampr.org domain is not well connected to internet, and it
is not contigiously connected itself.  So unless there is an amprnet to
internet gateway properly configured and operating near the destination
station, the mail will probably be bounced back to you.  A simple way to see
if a path exists to the station in question is to try doing a telnet to his
domain name or ip address.  If it results in a login prompt, then you should
also be able to send mail to the same address.  The only other gotcha is
that some gateway operators restrict which services pass through their
gateway, to avoid hearing from FCC...

I don't know much about packet but I do have a Baycom BP-1 TNC/Modem and
it works fine with my 386/dx25.  I wonder if a change of software will
give me any better features with the Baycom or is it dependent on the
software that came with it?

I'll find all this out eventually on my own, as the companys who make

is such a great resource for newcomers to the field.

Post a question in comp.os.linux.help and I bet you get an answer.

Subject: Hamcomm interface problems
To: [e-mail]

[I tried sending this privately, but it bounced.  It's good general advice
on HC anyway...DM]


I'd recommend trying these steps to get your converter going:

1) Get the latest HamComm, 3.0, which is at oak.oakland.edu.

2) Try hooking up the box using the program's default com port
selections as they come out of the archive;  when trying lots of
different configurations, it's easy to lose sight, and you need to
start fresh every so often.

2A) Pay special attention to the com port addresses and IRQs;  if these
are incorrect, you'll get no output to the program.

3) Check the voltages to the 741, particularly the diode bridge.  The
HamComm 3.0 docs have a good section on troubleshooting.

3A) You may need to power the 741 externally;  the HC 3.0 docs have
a schematic for such modifications.

4) If the box is working correctly, you should see noise (random dots)
on the scope (F8) display.

That being said, I have been using the same homebuilt decoder since
HamComm 2.0, and I have not had a problem.  The only change I will make
to my box is to put a TL071 op-amp, which is considerably more sensitive
than the 741.

Have you tried to follow the instructions in the manual section on
troubleshooting? There are many variations of circuits with just one
op-amp floating around.  The problem is, that most of them where meant
for receive only.  HamComm also transmits and has to pull the PTT and
FSK line.  To keep the op-amp happy the HamComm interface has a bridge
rectifier made from 4 diodes.  For a start, check the supply voltages at
the op-amp for correct polarity.  Also make sure the op-amp output is
really connected to DSR.

What version?   The current version is 3.0.

Not unless someone does a special version for it.  AEA TNCs are >not< TNC2
clones.  I don't even think the special version of NET/ROM that was done for
the PK-88 will work in the PK-96, because of the new dual-modem hardware.

TAPR use to offer a TNC-1 upgrade kit, which upgraded the TNC-1 into a
TNC-2 system (Z80 and all).  This would then be capable of running any
TCN-2 firmware.

We stopped offering it several years ago, but seems like there might be
interest in just bare boards with the instructions.

If this would help anyone - let me know and I'll see if I can get the
TAPR board to spring for a limited board run for just bare boards as
kit.  There is nothing really hard to find on the board - would probably
have to include the 1.1.8a firmware along with the set.

I would be interesting in getting input on this.  If there is enough
interest we might do something.

Cheers - Greg

Wrong.  Standard channelization is as old as the birth of broadcasting when it
was realized that something had to be done to control the frequency
allocations for the fledgling AM broadcast industry.  It is the easy way out
for narrow band VHF operations.  Amateur operation on HF has been an example
of how to share and conserve spectrum resources in an orderly fashion without
channelization.  As you pointed out just because your VFO has 10 Hz readout
doesn't mean there are 10 Hz wide channels on HF for your use.  But, if
stations in QSO need to move 100 Hz to get away from a foreign broadcast
carrier in region 2 then they can without worrying about changing channels.

We are taking a giant step backward by bringing something as ancient as
channelization to the HF bands, only for a crutch for automated digital
operation.  This is particularly disappointing when the technology exists to
provide a more robust and automated hunting system using dynamic channel
centering.  Unfortunately when channelization is implemented there will be no
incentive to improve on it.  So the first wrung of the system will be obsolete
before it gets started.
